STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

This invention was made with government support under CA121279 awarded by the National Institutes of Health. The government has certain rights in the invention.

BACKGROUND

The aggressive cancer cell phenotype is the result of a variety of genetic and epigenetic alterations leading to deregulation of intracellular signaling pathways (Ponder, Nature 411:336 (2001)). Cancer cells typically fail to execute an apoptotic program, and lack of appropriate apoptosis due to defects in the normal apoptosis machinery is considered a hallmark of cancer (Lowe et al., Carcinogenesis 21:485 (2000)). The inability of cancer cells to execute an apoptotic program due to defects in the normal apoptotic machinery is often associated with an increase in resistance to chemotherapy, radiation, or immunotherapy-induced apoptosis. Primary or acquired resistance of human cancer of different origins to current treatment protocols due to apoptosis defects is a major problem in current cancer therapy (Lowe et al., Carcinogenesis 21:485 (2000); Nicholson, Nature 407:810 (2000)). Accordingly, current and future efforts towards designing and developing new molecular target-specific anticancer therapies to improve survival and quality of life of cancer patients must include strategies that specifically target cancer cell resistance to apoptosis.

The p53 tumor suppressor plays a central role in controlling cell cycle progression, senescence, and apoptosis (Vogelstein et al., Nature 408:307 (2000); Goberdhan, Cancer Cell 7:505 (2005)). MDM2 and p53 are part of an auto-regulatory feed-back loop (Wu et al., Genes Dev. 7:1126 (1993)). MDM2 is transcriptionally activated by p53 and MDM2, in turn, inhibits p53 activity by at least three mechanisms (Wu et al., Genes Dev. 7:1126 (1993). First, MDM2 protein directly binds to the p53 transactivation domain and thereby inhibits p53-mediated transactivation. Second, MDM2 protein contains a nuclear export signal sequence, and upon binding to p53, induces the nuclear export of p53, preventing p53 from binding to the targeted DNAs. Third, MDM2 protein is an E3 ubiquitin ligase and upon binding to p53 is able to promote p53 degradation.

Although high-affinity peptide-based inhibitors of MDM2 have been successfully designed in the past (Garcia-Echeverria et al., Med. Chem. 43:3205 (2000)), these inhibitors are not suitable therapeutic molecules because of their poor cell permeability and in vivo bioavailability. Despite intensive efforts by the pharmaceutical industry, high throughput screening strategies have had very limited success in identifying potent, non-peptide small molecule inhibitors. Accordingly, there is a need for non-peptide, drug-like, small molecule inhibitors of the p53-MDM2 interaction.

The structural basis of the interaction p53 and MDM2 has been established by x-ray crystallography (Kussie et al., Science 274:948 (1996)).

Spiro-oxindole-based antagonists of the p53-MDM2 interaction are described in U.S. Pat. Nos. 7,759,383 B2 and 7,737,174 B2.

Skin cancer or melanoma is a commonly found type of cancer. Even though melanoma represents only a small fraction of the total number of cancer cases, it is responsible for many cancer deaths. According to statistics provided by the American Cancer Society, in contrast to many other types of cancers, the number of new cases of melanoma in the United States is still on the rise.

As with all cancers, it is imperative to diagnose melanoma early. About 70% of melanomas are “superficial spreading”, meaning that they undergo a superficial, radial growth phase before they grow vertically and invade underlying tissue, a much more serious condition. Unfortunately, about 20% of cutaneous melanomas immediately start out with a vertical growth phase, which explains why these tumors are so dangerous. The 5-year survival rate for Stage 1 melanoma is very good. However, this drops off rapidly when cancer is allowed to progress and invade, first locally and then more distantly. Survival rate for Stage 2 disease is only 40-80%, Stage 3 10-70% and Stage 4 is almost invariably lethal within 5 years (<5-10% survives beyond 5 years) due to untreatable distant metastasis to especially lung and brain.

Melanoma originates from malignant transformation of melanocytes, the pigment producing skin cells, via atypical and dysplastic premalignant intermediate stages to locally invasive and finally metastatic melanoma. A large number of genes have been implicated to play a role in these processes. Metastatic melanoma, the usual cause of death, is notoriously resistant to conventional therapy.

SUMMARY OF THE INVENTION

The present disclosure contemplates that exposure of humans and animals to therapeutically effective amounts of drug(s) (e.g., small molecules) that increase the function(s) of p53 and p53-related proteins (e.g., p63, p73) inhibits the growth of p53 expressing cells. In some embodiments, the compounds provided herein inhibit the interaction between p53 or p53-related proteins and MDM2 or MDM2-related proteins (e.g., MDMX). Inhibiting the interaction between p53 or p53-related proteins and MDM2 or MDM2-related proteins inhibits the growth of cells. For example, inhibiting the interaction between p53 or p53-related proteins and MDM2 or MDM2-related proteins can inhibit cancer cells or supporting cells and/or renders such cells as a population more susceptible to the cell death-inducing activity of cancer therapeutic drugs or radiation therapies. In some embodiments, the inhibitors provided herein prolong the half-life of p53 by interfering with the p53-MDM2 interaction that would normally promote degradation of p53. The compounds provided herein satisfy an unmet need for the treatment of multiple cancer types, either when administered as monotherapy to induce senescence, cell growth inhibition, apoptosis and/or cell cycle arrest in cancer cells, or when administered in a temporal relationship with additional agent(s), such as other cell death-inducing or cell cycle disrupting cancer therapeutic drugs or radiation therapies (combination therapies), so as to render a greater proportion of the cancer cells or supportive cells susceptible to executing the apoptosis program compared to the corresponding proportion of cells in an animal treated only with the cancer therapeutic drug or radiation therapy alone.

In some embodiments, treatment of animals (including humans) with a therapeutically effective amount of one or more compounds provided herein and an anticancer agent produces a greater anti-tumor activity and clinical benefit in such animals compared to those treated with the compound or anticancer drugs/radiation alone. Put another way, because the compounds provided herein can lower the apoptotic threshold of cells that express p53 or p53-related protein, the proportion of cells that successfully execute the apoptosis program in response to the apoptosis inducing activity of anticancer drugs/radiation will be increased when used in combination with one or more of the compounds provided herein. Alternatively, the compounds provided herein can be used to allow administration of a lower, and therefore less toxic and more tolerable, dose of an anticancer drug and/or radiation to produce the same tumor response/clinical benefit as the conventional dose of the anticancer drug/radiation alone. Since the doses for all approved anticancer drugs and radiation treatments are known, the present compounds, compositions, and methods provided herein can be used with one or more approved anticancer drugs and/or radiation treatment. Also, since the compounds provided herein may act at least in part by stimulating the pro-apoptotic and/or cell cycle-inhibiting activities of p53 and p53-related proteins, the exposure of cancer cells and supporting cells to therapeutically effective amounts of the compounds can be temporally linked to coincide with the attempts of cells to execute the apoptosis program in response to the anticancer drug or radiation therapy. Thus, in some embodiments, administering the compounds or compositions provided herein in combination with other known anticancer drugs provide especially efficacious therapeutic practices.

In other embodiments, the inhibitors of the interaction between p53 or p53-related proteins and MDM2 and MDM2-related proteins provided herein may protect normal (e.g., non-hyperproliferative) cells from the toxic effects of certain chemotherapeutic agents and radiation, possibly through the ability of the inhibitors to induce cell cycle arrest of normal cells. For example, the inhibitors provided herein may cause cell cycle arrest in cells comprising wild-type or functional p53 (and/or wild-type or functional p53-related proteins) while having no or less effect on cancer cells comprising mutated, deleted, or otherwise non- or less functional p53 (and/or mutated, deleted, or otherwise non- or less functional p53-related proteins). This differential protective effect may allow for more effective treatment of cancer by allowing the use of higher doses or longer treatments of chemotherapeutic agents or treatments without increasing the toxic side effects of such treatment when administered in combination with inhibitors provided herein.

Applicants have found that certain spiro-oxindoles provided herein display an unexpected combination of drug-like properties. The unexpected combinations include, e.g., two or more of in vitro efficacy, in vivo efficacy, in vitro liver microsome stability, desirable absorption, distribution, metabolism, and excretion (ADME) properties. For example, certain spiro-oxindoles provided herein are more resistant to metabolic degradation e.g., as measured by in vitro liver microsomal stability and/or in vivo pharmacokinetics, and/or display improved in vivo efficacy as compared to known antagonists of the p53-MDM2 interaction.

Applicants have also found that metabolically cleavable groups can be used to increase the aqueous solubility of the parent molecule. Thus, in some embodiments, the spiro-oxindoles provided herein are useful prodrugs with improved aqueous solubility relative to the parent molecule.

In some embodiments, the compounds provided herein are spiro-oxindoles having Formulae I-XXXV (see below under “Compounds”), or pharmaceutically acceptable salts, solvates, or prodrugs thereof. In some embodiments, the compounds provided herein inhibit the interaction between p53 or p53-related proteins and MDM2 or MDM2-related proteins.

In some embodiments, the compounds provided herein contain a metabolically cleavable group. In particular, in some embodiments, the compounds provided herein contain a hydroxy group of a hydroxycycloalkyl side chain that can be used to attach a metabolically cleavable group. Suitable metabolically cleavable groups include, but are not limited to, amino acid esters or phosphate esters.

In some embodiments, the compounds provided herein can be used to induce senescence, cell cycle arrest and/or apoptosis in cells containing functional p53 or p53-related proteins. Also provided herein are methods of using the compounds provided herein for sensitizing cells to additional agent(s), such as inducers of senescence, apoptosis and/or cell cycle arrest. The compounds provided herein can also be used to provide chemoprotection of normal cells through the induction of cell cycle arrest prior to treatment with chemotherapeutic agents. In one embodiment, the methods of rendering a normal cell resistant to chemotherapeutic agents or treatments comprises contacting the cell with one or more compounds provided herein. In one embodiment, methods of protecting normal cells in an animal having a hyperproliferative disease from the toxic side effects of chemotherapeutic agents or treatments, comprises administering to the animal a compound provided herein. Provided herein are methods for the treatment, amelioration, or prevention of disorders, side effects, or conditions caused by the administration of chemotherapeutic agents to normal cells comprising administering to an animal undergoing chemotherapy a compound provided herein. Examples of such disorders and conditions caused by chemotherapy include, without limitation, mucositis, stomatitis, xerostomia, gastrointestinal disorders, and alopecia.

The compounds provided herein are useful for the treatment, amelioration, or prevention of disorders, such as those responsive to induction of apoptotic cell death, e.g., disorders characterized by dysregulation of apoptosis, including hyperproliferative diseases such as cancer. In certain embodiments, the compounds can be used to treat, ameliorate, or prevent cancer that is characterized by resistance to cancer therapies (e.g., those cancer cells which are chemoresistant, radiation resistant, hormone resistant, and the like). In other embodiments, the compounds can be used to treat hyperproliferative diseases characterized by expression of functional p53 or p53-related proteins. In other embodiments, the compounds provided herein can be used to protect normal (e.g., non-hyperproliferative) cells from the toxic side effects of chemotherapeutic agents and treatments by the induction of cell cycle arrest in those cells.

Definitions

The terms “pulsatile administration,” “pulsatile dose administration,” or “pulsatile dosing” as used herein, refer to intermittent (i.e., not continuous) administration of one or more of the compounds provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, to a patient. Pulsatile dose administration regimens useful in the present disclosure encompass any discontinuous administration regimen that provides a therapeutically effective amount of the compound(s) provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, to a patient in need thereof. Pulsatile dosing regimens can use equivalent, lower, or higher doses of compounds, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, than would be used in continuous dosing regimens. The compounds provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, can be administered as a single agent under a pulsatile dosing regimen or can be administered under a pulsatile dosing regimen in combination with one or more additional anticancer agents (where the additional anticancer agents are administered either on a continuous or a pulsatile regimen). On the day that compounds, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, are scheduled to be administered to the patient, administration can occur in a single or in divided doses, e.g., once-a-day, twice-a-day, three times a day, four times a day or more. In one embodiment, compounds provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, are administered once (QD) or twice (BID) on the day it is schedule to be administered. In one embodiment the compounds provided, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, are administered orally to the patient according to a pulsatile dosing regimen. In one embodiment the compounds provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, are administered intravenously to the patient according to a pulsatile dosing regimen.

The therapeutic utility of drug administration can be offset by the number and severity of adverse events a patient experiences. Pulsatile dosing of compounds provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, can result in a reduction in the number and/or severity of clinical adverse events coupled with a maintenance or enhancement in clinical efficacy, as compared to continuous daily dosing. The clinical benefits of pulsatile dose administration of compounds provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, can be more prominent when combined with the administration of other therapeutic agents to the patient.

In one embodiment, compounds provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, are administered to a patient no more frequently than one day out of every two days (e.g., administration occurs on day 1, day 3, day 5, day 7, day 9, etc.), one out of every three days (e.g., administration occurs on day 1, day 4, day 7, day 10, etc.), one out of every four days, one out of every five days, one out of every six days, one out of every seven days, one out of every eight days, one out of every nine days, one out of every ten days, one out of every two weeks, one out of every three weeks, one out of every four weeks, one out of every five weeks, or longer.

With every repetition any additional therapeutic agents may be the same or different from that used in the previous repetition.

In another embodiment, compounds provided herein, or pharmaceutically acceptable salts, solvates, or prodrugs thereof, are administered according to a pulsatile dosing schedule and/or sequential combination of two or more pulsatile dosing schedules followed by a waiting period. The term “waiting period,” as used herein, refers to a period of time between dosing schedules when a compound disclosed herein is not administered to the patient. The waiting period may be one, two, three, four, five or six days, one, two or three weeks, one, two, three or four months, one, two, three or four years or longer. In certain embodiments, the waiting period may be one to thirty days, e.g., seven, fourteen, twenty one or thirty days, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 or 30 days. After the waiting period, the same or a different pulsatile dosing schedule and/or sequential combination of one or more pulsatile dosing schedules of a compound disclosed herein can resume. The pulsatile dosing/waiting period regimen may be repeated as many times as necessary to achieve or maintain a therapeutic response, e.g., from one to about fifty times, e.g., from one to about twenty times, e.g., from about one to about ten times. With every repetition any additional therapeutic agents may be the same or different from that used in the previous repetition.

The term “anticancer agent” as used herein, refers to any therapeutic agent (e.g., chemotherapeutic compound and/or molecular therapeutic compound), antisense therapy, radiation therapy, or surgical intervention, used in the treatment of hyperproliferative diseases such as cancer (e.g., in mammals, e.g., in humans).

The term “prodrug” as used herein, refers to a pharmacologically inactive derivative of a parent “drug” molecule that requires biotransformation (e.g., either spontaneous or enzymatic) within the target physiological system to release, or to convert (e.g., enzymatically, physiologically, mechanically, electromagnetically) the prodrug into the active drug. Prodrugs are designed to overcome problems associated with stability, water solubility, toxicity, lack of specificity, or limited bioavailability. Exemplary prodrugs comprise an active drug molecule itself and a chemical masking group (e.g., a group that reversibly suppresses the activity of the drug). Some prodrugs are variations or derivatives of compounds that have groups cleavable under metabolic conditions. Prodrugs can be readily prepared from the parent compounds using methods known in the art, such as those described in A Textbook of Drug Design and Development, Krogsgaard-Larsen and H. Bundgaard (eds.), Gordon & Breach, 1991, particularly Chapter 5: “Design and Applications of Prodrugs”; Design of Prodrugs, H. Bundgaard (ed.), Elsevier, 1985; Prodrugs: Topical and Ocular Drug Delivery, K. B. Sloan (ed.), Marcel Dekker, 1998; Methods in Enzymology, K. Widder et al. (eds.), Vol. 42, Academic Press, 1985, particularly pp. 309-396; Burger's Medicinal Chemistry and Drug Discovery, 5th Ed., M. Wolff (ed.), John Wiley & Sons, 1995, particularly Vol. 1 and pp. 172-178 and pp. 949-982; Pro-Drugs as Novel Delivery Systems, T. Higuchi and V. Stella (eds.), Am. Chem. Soc., 1975; and Bioreversible Carriers in Drug Design, E. B. Roche (ed.), Elsevier, 1987.

Exemplary prodrugs become pharmaceutically active in vivo or in vitro when they undergo solvolysis under physiological conditions or undergo enzymatic degradation or other biochemical transformation (e.g., phosphorylation, hydrogenation, dehydrogenation, glycosylation). Prodrugs often offer advantages of water solubility, tissue compatibility, or delayed release in the mammalian organism. (See e.g., Bundgaard, Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam (1985); and Silverman, The Organic Chemistry of Drug Design and Drug Action, pp. 352-401, Academic Press, San Diego, Calif. (1992)). Common prodrugs include acid derivatives such as esters prepared by reaction of parent acids with a suitable alcohol (e.g., a lower alkanol) or esters prepared by reaction of parent alcohol with a suitable carboxylic acid, (e.g., an amino acid), amides prepared by reaction of the parent acid compound with an amine, basic groups reacted to form an acylated base derivative (e.g., a lower alkylamide), or phosphorus-containing derivatives, e.g., phosphate, phosphonate, and phosphoramidate esters, including cyclic phosphate, phosphonate, and phosphoramidate, see, e.g., US 2007/0249564 A1.

The term “metabolically cleavable group” as used herein, refers to groups which can be cleaved from the parent molecule by metabolic processes and be substituted with hydrogen. Certain compounds containing metabolically cleavable groups may be prodrugs, i.e., they are pharmacologically inactive. Certain other compounds containing metabolically cleavable groups may be antagonists of the interaction between p53 and MDM2. In such cases, these compounds may have more, less, or equivalent activity of the parent molecule. Examples of metabolically cleavable groups include those derived from amino acids (see, e.g., US 2006/0241017 A1; US 2006/0287244 A1; and WO 2005/046575 A2) or phosphorus-containing compounds (see, e.g., U.S. 2007/0249564 A1) as illustrated in Scheme 1.

It will be readily apparent to one of ordinary skill in the art that the compounds defined above can be synthesized by substitution of the appropriate reagents and agents in the syntheses shown below.

Compounds of Formula Ia wherein Y is NH can be synthesized as described in Schemes 2 and 3.

Compounds of Formula Ia can be separated by chiral resolution methods well known in the art, e.g., chiral column chromatography, to give compounds of Formulae II-XVII. Suitable chiral columns for use in chiral resolutions include, for example, Daicel CHIRALCEL®OD-H, Daicel CHIRALPAK® AD-H and Regis Technologies ULMO chiral columns. Other chiral resolution methods are also possible. Compounds of Formulae II-XVII can also be prepared by asymmetric synthetic methods. For example, compounds of Formula II, wherein Y is NH, can be synthesized by using a asymmetric 1,3-dipolar cycloaddition as the key step as previously described (See U.S. Pat. Nos. 7,759,383 B2 and 7,737,174 B2, and Ding et al., J. Am. Chem. Soc. 127:10130-10131 (2005)) (Scheme 4).

For a more detailed description of anticancer agents and other therapeutic agents, those skilled in the art are referred to any number of instructive manuals including, but not limited to, the Physician's Desk Reference and to Goodman and Gilman's “Pharmaceutical Basis of Therapeutics” tenth edition, Eds. Hardman et al., 2002.

In some embodiments, methods provided herein, including the methods comprising pulsatile dose administration, comprise administering one or more compounds provided herein with radiation therapy. The methods provided herein are not limited by the types, amounts, or delivery and administration systems used to deliver the therapeutic dose of radiation to an animal. For example, the animal may receive photon radiotherapy, particle beam radiation therapy, other types of radiotherapies, and combinations thereof. In some embodiments, the radiation is delivered to the animal using a linear accelerator. In still other embodiments, the radiation is delivered using a gamma knife.

The source of radiation can be external or internal to the animal. External radiation therapy is most common and involves directing a beam of high-energy radiation to a tumor site through the skin using, for instance, a linear accelerator. While the beam of radiation is localized to the tumor site, it is nearly impossible to avoid exposure of normal, healthy tissue. However, external radiation is usually well tolerated by animals. Internal radiation therapy involves implanting a radiation-emitting source, such as beads, wires, pellets, capsules, particles, and the like, inside the body at or near the tumor site including the use of delivery systems that specifically target cancer cells (e.g., using particles attached to cancer cell binding ligands). Such implants can be removed following treatment, or left in the body inactive. Types of internal radiation therapy include, but are not limited to, brachytherapy, interstitial irradiation, intracavity irradiation, radioimmunotherapy, and the like.

The animal may optionally receive radiosensitizers (e.g., metronidazole, misonidazole, intra-arterial Budr, intravenous iododeoxyuridine (IudR), nitroimidazole, 5-substituted-4-nitroimidazoles, 2H-isoindolediones, [[(2-bromoethyl)-amino]methyl]-nitro-1H-imidazole-1-ethanol, nitroaniline derivatives, DNA-affinic hypoxia selective cytotoxins, halogenated DNA ligand, 1,2,4 benzotriazine oxides, 2-nitroimidazole derivatives, fluorine-containing nitroazole derivatives, benzamide, nicotinamide, acridine-intercalator, 5-thiotretrazole derivative, 3-nitro-1,2,4-triazole, 4,5-dinitroimidazole derivative, hydroxylated texaphrins, cisplatin, mitomycin, tiripazamine, nitrosourea, mercaptopurine, methotrexate, fluorouracil, bleomycin, vincristine, carboplatin, epirubicin, doxorubicin, cyclophosphamide, vindesine, etoposide, paclitaxel, heat (hyperthermia), and the like), radioprotectors (e.g., cysteamine, aminoalkyl dihydrogen phosphorothioates, amifostine (WR 2721), IL-1, IL-6, and the like). Radiosensitizers enhance the killing of tumor cells. Radioprotectors protect healthy tissue from the harmful effects of radiation.

Any type of radiation can be administered to an animal, so long as the dose of radiation is tolerated by the animal without unacceptable negative side-effects. Suitable types of radiotherapy include, for example, ionizing (electromagnetic) radiotherapy (e.g., X-rays or gamma rays) or particle beam radiation therapy (e.g., high linear energy radiation). Ionizing radiation is defined as radiation comprising particles or photons that have sufficient energy to produce ionization, i.e., gain or loss of electrons (as described in, for example, U.S. Pat. No. 5,770,581 incorporated herein by reference in its entirety). The effects of radiation can be at least partially controlled by the clinician. In one embodiment, the dose of radiation is fractionated for maximal target cell exposure and reduced toxicity.

In one embodiment, the total dose of radiation administered to an animal is about 0.01 Gray (Gy) to about 100 Gy. In another embodiment, about 10 Gy to about 65 Gy (e.g., about 15 Gy, 20 Gy, 25 Gy, 30 Gy, 35 Gy, 40 Gy, 45 Gy, 50 Gy, 55 Gy, or 60 Gy) are administered over the course of treatment. While in some embodiments a complete dose of radiation can be administered over the course of one day, the total dose is ideally fractionated and administered over several days. Desirably, radiotherapy is administered over the course of at least about 3 days, e.g., at least 5, 7, 10, 14, 17, 21, 25, 28, 32, 35, 38, 42, 46, 52, or 56 days (about 1-8 weeks). Accordingly, a daily dose of radiation will comprise approximately 1-5 Gy (e.g., about 1 Gy, 1.5 Gy, 1.8 Gy, 2 Gy, 2.5 Gy, 2.8 Gy, 3 Gy, 3.2 Gy, 3.5 Gy, 3.8 Gy, 4 Gy, 4.2 Gy, or 4.5 Gy), or 1-2 Gy (e.g., 1.5-2 Gy). The daily dose of radiation should be sufficient to induce destruction of the targeted cells. If stretched over a period, in one embodiment, radiation is not administered every day, thereby allowing the animal to rest and the effects of the therapy to be realized. For example, radiation desirably is administered on 5 consecutive days, and not administered on 2 days, for each week of treatment, thereby allowing 2 days of rest per week. However, radiation can be administered 1 day/week, 2 days/week, 3 days/week, 4 days/week, 5 days/week, 6 days/week, or all 7 days/week, depending on the animal's responsiveness and any potential side effects. Radiation therapy can be initiated at any time in the therapeutic period. In one embodiment, radiation is initiated in week 1 or week 2, and is administered for the remaining duration of the therapeutic period. For example, radiation is administered in weeks 1-6 or in weeks 2-6 of a therapeutic period comprising 6 weeks for treating, for instance, a solid tumor. Alternatively, radiation is administered in weeks 1-5 or weeks 2-5 of a therapeutic period comprising 5 weeks. These exemplary radiotherapy administration schedules are not intended, however, to limit the methods provided herein.

Antimicrobial therapeutic agents may also be used as therapeutic agents in combination with the compounds provided herein. Any agent that can kill, inhibit, or otherwise attenuate the function of microbial organisms may be used, as well as any agent contemplated to have such activities. Antimicrobial agents include, but are not limited to, natural and synthetic antibiotics, antibodies, inhibitory proteins (e.g., defensins), antisense nucleic acids, membrane disruptive agents and the like, used alone or in combination. Indeed, any type of antibiotic may be used including, but not limited to, antibacterial agents, antiviral agents, antifungal agents, and the like.

In some embodiments of the methods provided herein, one or more compounds provided herein and one or more therapeutic agents or anticancer agents are administered to an animal under one or more of the following conditions: at different periodicities, at different durations, at different concentrations, by different administration routes, etc. In some embodiments, the compound is administered prior to the therapeutic or anticancer agent, e.g., 0.5, 1, 2, 3, 4, 5, 10, 12, or 18 hours, 1, 2, 3, 4, 5, or 6 days, or 1, 2, 3, or 4 weeks prior to the administration of the therapeutic or anticancer agent. In some embodiments, the compound is administered after the therapeutic or anticancer agent, e.g., 0.5, 1, 2, 3, 4, 5, 10, 12, or 18 hours, 1, 2, 3, 4, 5, or 6 days, or 1, 2, 3, or 4 weeks after the administration of the anticancer agent. In some embodiments, the compound and the therapeutic or anticancer agent are administered concurrently but on different schedules, e.g., the compound is administered daily while the therapeutic or anticancer agent is administered once a week, once every two weeks, once every three weeks, or once every four weeks. In other embodiments, the compound is administered once a week while the therapeutic or anticancer agent is administered daily, once a week, once every two weeks, once every three weeks, or once every four weeks.

In some embodiments, compositions provided herein comprise one or more of the compounds provided herein in an amount which is effective to achieve its intended purpose. While individual needs vary, determination of optimal ranges of effective amounts of each component is within the skill of the art. Typically, the compounds may be administered to mammals, e.g. humans, orally at a dose of 0.0025 to 50 mg/kg, or an equivalent amount of the pharmaceutically acceptable salt thereof, per day of the body weight of the mammal being treated for disorders responsive to induction of apoptosis. In one embodiment, about 0.01 to about 25 mg/kg is orally administered to treat, ameliorate, or prevent such disorders. For intramuscular injection, the dose is generally about one-half of the oral dose. For example, a suitable intramuscular dose would be about 0.0025 to about 25 mg/kg, or from about 0.01 to about 5 mg/kg.

The unit oral dose may comprise from about 0.01 to about 1000 mg, for example, about 0.1 to about 100 mg of the compound. The unit dose may be administered one or more times daily as one or more tablets or capsules each containing from about 0.1 to about 10 mg, conveniently about 0.25 to 50 mg of the compound or its solvates.

In a topical formulation, the compound may be present at a concentration of about 0.01 to 100 mg per gram of carrier. In a one embodiment, the compound is present at a concentration of about 0.07-1.0 mg/ml, for example, about 0.1-0.5 mg/ml, and in one embodiment, about 0.4 mg/ml.

In addition to administering the compound as a raw chemical, the compounds provided herein may be administered as part of a pharmaceutical preparation or composition. In some embodiments, the pharmaceutical preparation or composition can include one or more pharmaceutically acceptable carriers, excipients, and/or auxiliaries. In some embodiments, the one or more carriers, excipients, and auxiliaries facilitate processing of the compound into a preparation or composition which can be used pharmaceutically. The preparations, particularly those preparations which can be administered orally or topically and which can be used for one type of administration, such as tablets, dragees, slow release lozenges and capsules, mouth rinses and mouth washes, gels, liquid suspensions, hair rinses, hair gels, shampoos and also preparations which can be administered rectally, such as suppositories, as well as suitable solutions for administration by intravenous infusion, injection, topically or orally, contain from about 0.01 to 99 percent, in one embodiment from about 0.25 to 75 percent of active compound(s), together with the one or more carriers, excipients, and/or auxiliaries.

The pharmaceutical compositions of provided herein may be administered to any patient which may experience the beneficial effects of the compounds provided herein. Foremost among such patients are mammals, e.g., humans, although the methods and compositions provided herein are not intended to be so limited. Other patients include veterinary animals (cows, sheep, pigs, horses, dogs, cats and the like).

The compounds and pharmaceutical compositions thereof may be administered by any means that achieve their intended purpose. For example, administration may be by parenteral, subcutaneous, intravenous, intramuscular, intraperitoneal, transdermal, buccal, intrathecal, intracranial, intranasal or topical routes. Alternatively, or concurrently, administration may be by the oral route. The dosage administered will be dependent upon the age, health, and weight of the recipient, kind of concurrent treatment, if any, frequency of treatment, and the nature of the effect desired.

The pharmaceutical preparations provided herein are manufactured by means of conventional mixing, granulating, dragee-making, dissolving, or lyophilizing processes. Thus, pharmaceutical preparations for oral use can be obtained by combining the active compounds with solid excipients, optionally grinding the resulting mixture and processing the mixture of granules, after adding suitable auxiliaries, if desired or necessary, to obtain tablets or dragee cores.

Suitable excipients are, in particular, fillers such as saccharides, for example lactose or sucrose, mannitol or sorbitol, cellulose preparations and/or calcium phosphates, for example tricalcium phosphate or calcium hydrogen phosphate, as well as binders such as starch paste, using, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, tragacanth, methyl cellulose, hydroxypropylmethylcellulose, sodium carboxymethylcellulose, and/or polyvinyl pyrrolidone. If desired, disintegrating agents may be added such as the above-mentioned starches and also carboxymethyl-starch, cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof, such as sodium alginate. Auxiliaries can be suitable flow-regulating agents and lubricants. Suitable auxiliaries include, for example, silica, talc, stearic acid or salts thereof, such as magnesium stearate or calcium stearate, and/or polyethylene glycol. Dragee cores are provided with suitable coatings which, if desired, are resistant to gastric juices. For this purpose, concentrated saccharide solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, polyethylene glycol and/or titanium dioxide, lacquer solutions and suitable organic solvents or solvent mixtures. In order to produce coatings resistant to gastric juices, solutions of suitable cellulose preparations such as acetylcellulose phthalate or hydroxypropylmethyl-cellulose phthalate, are used. Dye stuffs or pigments may be added to the tablets or dragee coatings, for example, for identification or in order to characterize combinations of active compound doses.

Other pharmaceutical preparations which can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer such as glycerol or sorbitol. The push-fit capsules can contain the active compounds in the form of granules which may be mixed with fillers such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds are in one embodiment dissolved or suspended in suitable liquids, such as fatty oils, or liquid paraffin. In addition, stabilizers may be added.

Possible pharmaceutical preparations which can be used rectally include, for example, suppositories, which consist of a combination of one or more of the active compounds with a suppository base. Suitable suppository bases are, for example, natural or synthetic triglycerides, or paraffin hydrocarbons. In addition, it is also possible to use gelatin rectal capsules which consist of a combination of the active compounds with a base. Possible base materials include, for example, liquid triglycerides, polyethylene glycols, or paraffin hydrocarbons.

Suitable formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form, for example, water-soluble salts and alkaline solutions. In addition, suspensions of the active compounds as appropriate oily injection suspensions may be administered. Suitable lipophilic solvents or vehicles include fatty oils, for example, sesame oil, or synthetic fatty acid esters, for example, ethyl oleate or triglycerides or polyethylene glycol-400. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension including, for example, sodium carboxymethyl cellulose, sorbitol, and/or dextran. Optionally, the suspension may also contain stabilizers.

The topical compositions provided herein are formulated in one embodiment as oils, creams, lotions, ointments and the like by choice of appropriate carriers. Suitable carriers include vegetable or mineral oils, white petrolatum (white soft paraffin), branched chain fats or oils, animal fats and high molecular weight alcohol (greater than C₁₂). The carriers may be those in which the active ingredient is soluble. Emulsifiers, stabilizers, humectants and antioxidants may also be included as well as agents imparting color or fragrance, if desired. Additionally, transdermal penetration enhancers can be employed in these topical formulations. Examples of such enhancers can be found in U.S. Pat. Nos. 3,989,816 and 4,444,762.

Ointments may be formulated by mixing a solution of the active ingredient in a vegetable oil such as almond oil with warm soft paraffin and allowing the mixture to cool. A typical example of such an ointment is one which includes about 30% almond oil and about 70% white soft paraffin by weight. Lotions may be conveniently prepared by dissolving the active ingredient, in a suitable high molecular weight alcohol such as propylene glycol or polyethylene glycol.

EXAMPLE 2 Fluorescence-polarization MDM2 Binding Assay

The binding affinity of the MDM2 inhibitors was determined using an optimized, sensitive and quantitative fluorescence polarization-based (FP-based) binding assay using a recombinant human His-tagged MDM2 protein (residues 1-118) and a fluorescently tagged p53-based peptide.

The design of the fluorescence probe was based upon a previously reported high-affinity p53-based peptidomimetic compound (5-FAM-βAla-βAla-Phe-Met-Aib-pTyr-(6-Cl-LTrp)-Glu-Ac3c-Leu-Asn-NH₂ (SEQ ID NO: 1)) (García-Echeverría et al., J. Med. Chem. 43: 3205-3208 (2000)). This tagged peptide is called PMDM6-F. The K_(d) value of PMDM6-F with the recombinant MDM2 protein was determined from the saturation curve. MDM2 protein was serially double diluted in a Dynex 96-well, black, round-bottom plate, and the PMDM6-F peptide was added at 1 nM concentration. The assay was performed in the buffer: 100 mM potassium phosphate, pH 7.5; 100 μg/mL bovine gamma globulin; 0.02% sodium azide, 0.01% Triton X-100) and the polarization values were measured after 3 h of incubation using an ULTRA READER (Tecan U.S. Inc., Research Triangle Park, N.C.). The IC₅₀ value was obtained by fitting the mP values in a sigmoidal dose-response curve (variable slope) with a non-linear regression, and was determined to be 1.40 nM±0.25. The K_(d) value was calculated using the equation: K_(d) value=IC₅₀−L0/2. L0 is the total concentration of the fluorescent ligand; L0/2 is the total concentration of the fluorescent ligand divided by 2. Since PMDM6-F was used at a final concentration of 1 nM, L0/2 was 0.5 nM.

Dose-dependent, competitive binding experiments were performed with serial dilutions of a tested compound in DMSO. A 5 μL sample of the tested compound and pre-incubated MDM2 protein (10 nM) and PMDM6-F peptide (1 nM) in the assay buffer (100 mM potassium phosphate, pH 7.5; 100 μg/mL bovine gamma globulin; 0.02% sodium azide, 0.01% Triton X-100), were added in a Dynex 96-well, black, round-bottom plate to produce a final volume of 125 μL. For each assay, the controls included the MDM2 protein and PMDM6-F (equivalent to 0% inhibition), PMDM6-F peptide alone (equivalent to 100% inhibition). The polarization values were measured after 3 h of incubation. The IC₅₀ values, i.e. the inhibitor concentration at which 50% of bound peptide is displaced, were determined from a plot using nonlinear least-squares analysis. Curve fitting was performed using GRAPHPAD PRISM software (GraphPad Software, Inc., San Diego, Calif.).

In the alternative, fluorescence polarization values were measured using the Infinite M-1000 plate reader (Tecan U.S., Research Triangle Park, N.C.) in Microfluor 2 96-well, black, round-bottom plates (Thermo Scientific). In the saturation experiments, 1 nM of PMDM6-F and increasing concentrations of proteins were added to each well to a final volume of 125 μl in the assay buffer (100 mM potassium phosphate, pH 7.5, 100 μg/ml bovine γ-globulin, 0.02% sodium azide (Invitrogen), with 0.01% Triton X-100 and 4% DMSO). Plates were mixed and incubated at room temperature for 30 minutes with gentle shaking to assure equilibrium. The polarization values in millipolarization units (mP) were measured at an excitation wavelength of 485 nm and an emission wavelength of 530 nm. Equilibrium dissociation constants (K_(d)) were then calculated by fitting the sigmoidal dose-dependent FP increases as a function of protein concentrations using Graphpad Prism 5.0 software (Graphpad Software, San Diego, Calif.).

K_(i) values of tested compounds were determined in a dose-dependent competitive binding experiment. Mixtures of 5 μl of the tested compound in different concentrations in DMSO and 120 μl of preincubated protein/fluorescent probe complex with fixed concentrations in the assay buffer (100 mM potassium phosphate, pH 7.5, 100 μg/ml bovine γ-globulin, 0.02% sodium azide, with 0.01% Triton X-100) were added into assay plates and incubated at room temperature for 30 minutes with gentle shaking. Final concentrations of the protein and fluorescent probe in the competitive assays were 10 nM and 1 nM, respectively, and final DMSO concentration is 4%. Negative controls containing protein/fluorescent probe complex only (equivalent to 0% inhibition), and positive controls containing free fluorescent probe only (equivalent to 100% inhibition), were included in each assay plate. FP values were measured as described above. IC₅₀ values were determined by nonlinear regression fitting of the sigmoidal dose-dependent FP decreases as a function of total compound concentrations using Graphpad Prism 5.0 software (Graphpad Software, San Diego, Calif.). K_(i) values of tested compounds to the MDM2 protein were calculated using the measured IC₅₀ values, the K_(d) value of the fluorescent probe to the protein, and the concentrations of the protein and fluorescent probe in the competitive assays (Nikolovska-Coleska et al., Anal. Biochem. 332:261-73 (2004)).

Compounds shown in Table 2A as the free base were tested either as the free base or as the CF₃CO₂H (TFA) or HCl salt. In general, comparable assay responses are expected between the free base and salt form of a compound (See, e.g., MI-77301 (free base) and MI-77301 (TFA salt)).

Binding Kinetics of Different Isomers in Binding Media

Aliquots of freshly prepared DMSO stock solutions of compounds were diluted in FP binding assay buffer to prepare the aqueous compound incubation solutions in which compound isomerization was taking place. Final compound concentration in the incubation solution was 25 μM, and 5% of DMSO was present to enhance the solubility. These solutions were stored at room temperature for the whole time range of the experiment. 80 μL of aliquots of compound solutions were mixed with 20 μL of freshly prepared MDM2/PMDM6-F mixture in the assay plates at different time points. Final concentrations of the protein, fluorescent probe, and DMSO are same as those in the competitive assays described above. Negative and positive controls were included in each assay plate as well. Following 15 minutes of incubation at room temperature with gentle shaking, mP values were measured and IC₅₀ values were determined as described above (Table 2B). Due to the plate preparation and incubation time required before measurement, it should be noticed that all IC₅₀ values presented below are values actually obtained 20 minutes after the labeled incubation time.

EXAMPLE 3 Fluorescence-polarization MDM2 Binding Assay

The binding affinity of the MDM2 inhibitors was optionally determined using a fluorescence polarization-based (FP-based) binding assay using a recombinant human MDM2 protein (residues 5-109) and PMDM6-F as follows:

MDM2 protein was serially diluted with a step of 1.8 in a Costar 96-well, black, non binding surface reference 3686 plate, and the PMDM6-F peptide was added at 5 nM concentration. The assay was performed in the buffer: 100 mM potassium phosphate, pH 7.5; 100 μg/mL bovine gamma globulin, 0.01% Triton X-100) and the anisotropy values were measured at equilibrium using a Fusion reader (Packard). The fraction of ligand bound, F_(SB), was calculated using the following equation F_(SB)=(Aobs−AF)/[(Ab−Aobs)Q+Aobs−AF](ref) where Aobs=anisotropy observed, Ab=anisotropy when all p53 is bound, AF=anisotropy when p53 is free, Q=ratio Fluorescence intensity Bound/fluorescence intensity Free (Biochemistry 43:16056-16066 (2004)). KD was determined, using the Langmuir equation applied to fluorescence polarization, to be 1.8 nM.

Dose-dependent, competitive binding experiments were performed with serial dilutions of a tested compound in DMSO. A 5 μL sample of the tested compound and PMDM6-F peptide (5 nM) and MDM2 protein (6 or 8 nM) in the assay buffer (100 mM potassium phosphate, pH 7.5; 100 μg/mL bovine gamma globulin, 0.01% Triton X-100), were added in Costar 96-well, black, non binding surface reference 3686 to produce a final volume of 125 μL. For each assay, the controls included the MDM2 protein and PMDM6-F (equivalent to 0% inhibition), PMDM6-F peptide alone (equivalent to 100% inhibition). The polarization values were measured at equilibrium. The IC₅₀ values, i.e. the inhibitor concentration at which 50% of bound peptide is displaced, were determined from a plot using the 4-parameter logistic model (Ratkowsky and Reedy, Biometrics 42(3):575-82 (1986). The adjustment was obtained by non-linear regression using the Marquardt algorithm in Xlfit software (Table 3).

EXAMPLE 4 Cell Growth Assay

Isogenic HCT-116 colon cancer cell lines were a kind gift from Prof. Bert Vogelstein (Johns Hopkins, Baltimore, Md.) and were maintained in McCoy's 5A medium containing 10% FBS. All other cell lines were obtained from ATCC (Manassas, Va.) and were maintained in RPMI-1640 medium containing 10% FBS.

Cells were seeded in 96-well flat bottom cell culture plates at a density of 2-3×10³ cells/well with compounds and incubated for 4 days. The rate of cell growth inhibition after treatment with increasing concentrations of the tested compounds was determined by WST-8 (2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium monosodium salt (Dojindo Molecular Technologies Inc., Gaithersburg, Md.). WST-8 was added at a final concentration of 10% to each well, and then the plates were incubated at 37° C. for 2-3 hrs. The absorbance of the samples was measured at 450 nm using a TECAN ULTRA Reader. The concentration of the compounds that inhibited cell growth by 50% (IC₅₀) was calculated by comparing absorbance in the untreated cells and the cells treated with the compounds using the GraphPad Prism software (GraphPad Software, La Jolla, Calif. 92037, USA). The results of this assay are presented in Tables 2A and 2C. Under conditions used in this assay, it is possible that a compound having Formula II isomerizes to a compound having Formula XII and other isomers (e.g., MI-773 isomerizes to MI-77301; MI-519-64 isomerizes to MI-519-6401). The results of this assay for MI-77301 in a variety of melanoma cell lines (Fernandez, Y., et al., Cancer Res. 65:6294-6304 and references cited therein) is presented in FIG. 24.

EXAMPLE 5 Cell Death Assay

Cell death assays were performed using trypan blue staining. Cells were treated in the presence and absence of indicated compounds. Both the floating and adherent cells were stained with trypan blue. Cells that stained blue or the morphologically unhealthy cells were scored as dead cells. At least 100 cells were counted in each of three separate areas under microscope. As shown in FIGS. 11 and 12, MDM2 inhibitors provided herein induce cell death in SJSA-1 and RS4;11 cancer cells with wild-type p53.

EXAMPLE 6 Western Blotting

For Western blot analysis, cells were lyzed in ice-cold RIPA buffer: 20 mM Tris-HCl (pH 7.5), 150 mM NaCl, 1 mM EDTA, 1 mM EGTA, 1% sodium deoxycholate, 2.5 mM sodium pyrophosphate, 1 mM b-glycerophosphate, 1 mM sodium orthovanadate and 1 μg/ml leupeptin. The proteins in the whole cell lysates were detected by Western blot analysis using the following antibodies: anti-p53 (clone DO-1), anti-MDM2 (clone SMP-14), anti-p21 (clone SX118), anti-β-actin (clone AC-40) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH; HRP conjugated). As shown in FIGS. 8, 9, and 13-16, MDM2 inhibitors provided herein are active in this assay.

PARP cleavage was used as a biochemical marker of apoptosis. During apoptosis, caspases cleave Poly(ADP-ribose)polymerase (PARP). Rabbit anti-PARP (Cell Signaling Cat #9542), used in the experiment, detects cleavage of full length (116 kD) Poly(ADP-ribose)polymerase (PARP) and larger (89 kD) cleaved fragment of PARP. A total of 2×10⁶ adherent cells were treated in the presence or absence of MI-77301 and incubated at 37° C. for 19 hr. Cells were harvested using 0.05% trypsin-EDTA (Invitrogen), washed in PBS and lysed on ice for 15 min using RIPA buffer (Sigma), supplemented with protease inhibitor cocktail (Roche). Clarified cell lysate was obtained by centrifuging the lysed cells at 13000×g at 4° C. for 15 min. Protein in the cell lysate was estimated using commercially available Bio-Rad protein assay dye. A total of 25 μg protein was loaded on a 4-20% SDS-PAGE gel, electrophoresed, and transferred to a PVDF membrane for 3 hours at 40 V. Membrane was blocked in TBST (20 mM Tris, 0.5 M NaCl, 0.1% Tween-20, pH 7.5) containing 5% dry milk (Bio-Rad) for 1 hr at room temperature. Primary antibody diluted in TBST, containing 5% dry milk, was applied to the membrane overnight in cold room at 4° C. on an orbital shaker. Membrane was washed in TBST, incubated for 1 hr at room temperature with either an anti-rabbit secondary antibody (Immunopure goat anti-rabbit antibody, Thermo Scientific) or an anti-mouse antibody (Pierce goat anti-mouse antibody, Thermo Scientific), diluted 1:2000 in TBST. Membrane was washed in TBST and developed using SuperSignal West Pico reagent (Thermo Scientific). Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) antibody conjugated to HRP (Santa Cruz) was used as a loading control for proteins. Western blot analyses for MI-77301 are provided in FIGS. 25, 26, and 28.

EXAMPLE 7 In vivo Efficacy Studies Using SJSA-1 and 22Rv1 Xenograft Models

SJSA-1 (osteosarcoma) tumor cells were harvested with Trypsin (0.05%)-EDTA (0.53 mM) (GIBCO™, Invitrogen Corp.), growth medium added and cells placed on ice. A cell sample was mixed 1:1 with Trypan Blue (GIBCO™, Invitrogen Corp.) and counted on a hemocytometer to determine the number of live/dead cells. Cells were washed once with 1×PBS (GIBCO™, Invitrogen Corp.) and resuspended in PBS. For Matrigel injections, after washing in PBS, cells are resuspended in an ice cold mixture of 1:1 PBS and Matrigel (BD Biosciences, Invitrogen Corp.) for a final Matrigel protein concentration of 5 mg/ml. SJSA-1 tumors were inoculated into C.B-17 SCID mice at 5×10⁶ cells in 0.1 ml with Matrigel. Cells were injected s.c. into the flank region of each mouse using a 27 gauge needle.

The size of tumors growing in the mice was measured in two dimensions using calipers. Tumor volume (mm³)=(A×B²)/2 where A and B are the tumor length and width (in mm), respectively. During treatment, tumor volume and body weight was measured three times a week. After the treatment was stopped, tumor volume (FIGS. 17, 20, 22, and 23) and body weight (FIGS. 18 and 21) was measured at least once a week. Mice were kept for an additional 60 days for further observation of tumor growth and toxicity. As shown in FIG. 22, a single 200 mg/kg dose of MI-77301 (QD1 treatment) shows comparable efficacy to a continuous dosing regimen (QD7 treatment).

Before treatment began, tumors were allowed to grow to 60-140 mm³ in volume, at which point the blood vessel supplies to the tumor should have been established. Mice with tumors within acceptable size range were randomized into treatment groups of 8 mice for experimental compounds and 10 mice for the Control group. Experimental compounds were given orally, once per day for 2-3 weeks. The Control group received vehicle alone (10% PEG 400:3% Cremophor:87% PBS). Other suitable vehicles for in vivo administration of the compounds provided herein include, without limitation, 98% PEG 200:2% polysorbate 80; 98% PEG 200:2% TPGS; and 0.5% polysorbate 80:0.6% methyl cellulose:98.9% water.

EXAMPLE 16 Isomerization Studies

General Information

Experiments involving moisture and/or air sensitive components were performed in oven-dried glassware under an atmosphere of nitrogen. Commercial solvents and reagents were used without further purification with the following exception: THF was freshly distilled from sodium wire.

Flash chromatography was performed using silica gel (type H) from TM chemicals, Inc. Columns were typically packed as slurry and equilibrated with hexane prior to use. Analytical thin layer chromatography (TLC) was performed using Merck 60 F254 precoated silica gel plate (0.2 mm thickness). Subjected to elution, plates were visualized using UV radiation. Further visualization was possible by staining with basic solution of potassium permanganate or acidic solution of phosphomolybdic acid, followed by heating with heating gun.

Compounds were purified by HPLC using a Waters Sunfire C18 reverse phase semipreparative HPLC column (19 mm×150 mm) using solvent A (water, 0.1% of TFA) and solvent B (CH₃CN, 0.1% of TFA or MeOH, 0.1% of TFA) as eluents with a flow rate of 10 mL/min on a Waters Delta 600 instrument. Analytical reverse phase HPLC was conducted using Waters 2795 Separation module.

Proton nuclear magnetic resonance (¹H NMR) and carbon nuclear magnetic resonance (¹³C NMR) spectroscopy were performed on a Bruker Advance 300 NMR spectrometer. Chemical shifts of ¹H NMR spectra are reported as δ in units of parts per million (ppm) downfield from SiMe₄ (δ 0.0) or relative to the signal of chloroform-d (δ=7.26, singlet), methanol-d₄ (δ=3.31, quintuplet) and DMSO-d₆ (δ=2.50, quintuplet). Multiplicities were given as: s (singlet); d (doublet); t (triplet); q (quartet); dd (doublet of doublets); ddd (doublet of doublets of doublets); dt (doublet of triplets); m (multiplets) and etc. The number of protons for a given resonance is indicated by nH. Coupling constants are reported as J values in Hz. Carbon nuclear magnetic resonance spectra (¹³C NMR) are reported as δ in units of parts per million (ppm) downfield from SiMe₄ (δ 0.0) or relative to the signal of chloroform-d (δ=77.23, triplet), MeOH-d₄ (δ=49.20, septuplet) and DMSO-d₆ (δ=39.52, septuplet).

Low resolution ESI mass spectrum analysis was performed on Thermo-Scientific LCQ Fleet mass spectrometer.

Compounds 1-10 were prepared according to Scheme 10 and Table 4 using methods previous described (See, e.g., Ding, K. et al., J. Am. Chem. Soc. 127:10130-10131 (2005); Ding, K. et al., J. Med. Chem. 49:3432-3435 (2006); Yu, S. et al., J. Med. Chem. 52:7970-7973 (2009); Shangary, S., Proc. Natl. Acad. Sci. 105:3933-3938 (2008); U.S. Pat. No. 7,759,383) as a mixture of isomers. Isomer A was identified as the predominant isomer following CAN oxidation in most cases. Applicants have found that dissolving the mixture of isomers obtained from CAN oxidation in a solvent or a mixture of solvents and allowing the reaction mixture to mature for a period of time under various conditions provides a mixture of isomers having Isomer B as the predominant isomer. In some cases, Isomers C and D were isolated in pure or substantially pure form. Likewise, compounds 11 and 12 were prepared according to Scheme 11 and Table 5.

The procedure for isomerization used in this study was as follows: approximately 30 mg product obtained from CAN oxidation (pre-purified by flash column chromatography) was placed in a round bottom flask equipped with magnetic stirring bar. Acetonitrile (2.4 mL) was added to dissolve the product. To the acetonitrile solution was added water (2.0 mL) and 0.5 mL NaHCO₃ (saturated) solution to give a pH of approximately 8. The reaction mixture was allowed to stir at room temperature for approximately 3 days. The percentage of isomers was determined using analytical HPLC. Further purification was performed on semi-preparative or preparative reverse phase HPLC using MeOH (0.1% TFA) and water (0.1% TFA) as mobile phase.

Isomerization of Isomer A to Isomer B can also be carried out under acidic conditions, e.g., MeCN—H₂O, CF₃CO₂H (pH<1), room temperature, 3 days; ethyl acetate, acetic acid, 60° C., 3 h, or neutral conditions e.g., MeOH or MeOH—H₂O.

EXAMPLE 23 Cell Growth Inhibition and Cytotoxic Effects on 22Rv1 Cell Lines

MI-519-6401 and MI-77301 were evaluated for their cell growth inhibition and cytotoxic effects on a prostate cancer cell line 22Rv1 (from The DSMZ—Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, reference DSMZ ACC438). For growth inhibition assays, cells were incubated in the presence of MI-519-6401 or MI-77301 for 96 h in 96-well format. Cell seeding conditions were adapted to get significant cell growth in this assay format. Growth inhibition assays were performed using the Celltiter-Glo Luminescent kit (Promega). The IC₅₀ values (concentration where the growth inhibition percentage is equal to half of the maximum inhibitory effect of the tested compound) were calculated and ranged between 100 nM and 500 nM in this prostate cancer cell line for both compounds.

For cytotoxicity assays, cells were incubated with MI-519-6401 or MI-77301 for 96 h in 6-well format. Cell seeding conditions were adapted to get significant cell growth in this assay format. Cytotoxic effects were measured using trypan blue staining. Both the floating and adherent cells were stained with trypan blue. Quantification was performed by Vi-CELL® Cell Viability Analyzer (Beckmann-Coulter) which determines both cell concentration and percentage of viable cells. For both compounds at concentrations which were close to IC₉₀ concentrations (concentration where the growth inhibition percentage is equal to 90 percent of the maximum inhibitory effect of the tested compound), the percentages of viable cells were significantly decreased compared to untreated cells and were at best between 50 and 70% in the 22Rv1 cell line.

EXAMPLE 24 Apoptosis Assay

Apoptosis was determined using Annexin-V-FLUOS/propidium iodide staining kit (Roche Applied Science) by modifications of the manufacturer's instructions. Early stage apoptotic cells display translocation of phosphatidylserine from inner to outer surface of plasma membrane which can be detected by Annexin V fluorescein staining. Propidium iodide (PI) staining determines the late stage apoptotic cells or necrotic cells. A total of 0.25×10⁶ cells were plated overnight in a 6-well tissue culture. Next day, adherent cells were treated in the presence or absence of MI-77301 and incubated at 37° C. for 2.5 days. Cells were harvested using 0.05% trypsin-EDTA (Invitrogen) by pooling the floating and the adherent cell populations, and were washed with PBS. Next, cells were stained with Annexin-V-FLUOS and PI in the incubation buffer at room temperature for 10 minutes in the dark. Modifications were made by using 0.5 μl each of Annexin-V-FLUOS and PI (instead of 2 μl each, mentioned in the instruction manual) for staining. These modifications were found to decrease the background noise, especially of fluorescein, in the assay. Cells were acquired and analyzed in a flow cytometer. Annexin V+/PI− cells were scored as early apoptotic cells and Annexin V+/PI+ cells as late apoptotic cells. The results of this assay are presented in FIG. 27.

EXAMPLE 25 In vivo Efficacy in the SK-Mel-103 Xenograft Model in Mice

Drug Preparation

MI-77301 was dissolved in 10% PEG400 (polyethylene glycol, mol wt 400, Sigma #P3265) 3% Cremophor EL (Sigma #C5135) and 87% 1×PBS (GIBCO™, Invitrogen Corp.) at the desired concentration (prepared fresh each day and dosed orally within 1 hour). The pH of the drug solutions were checked before use and required to be between pH 3.0 and 9.0 for PO (oral gavage) and between pH 4.5 and 9.0 for IV (intravenous) administration. The pH of a solution was adjusted with 0.5N NaOH when necessary.

Cell Culture

Human melanoma cells SK-MEL-103 were maintained at 37° C., 95% air, 5% carbon dioxide in HyQ® RPMI-1640 medium (with 2.05 mM L-glutamine, 0.1 μM sterile filtered, Hyclone®, QB Perbio) supplemented with 10% FBS and penicillin/streptomycin and passaged twice weekly.

Xenograft Tumor Cell Injection

Tumor cells for xenografts were harvested with Trypsin (0.05%)-EDTA (0.53 mM) (GIBCO™, Invitrogen Corp.), growth medium added and cells placed on ice. A cell sample was mixed 1:1 with Trypan Blue (GIBCO™, Invitrogen Corp.) and counted on a hemocytometer to determine the number of live/dead cells. Cells were washed once with 1×PBS (GIBCO™, Invitrogen Corp.) and resuspended in PBS. Cells in 0.1 ml were injected subcutaneously (s.c.) into the flank region of each mouse using a 27 gauge needle. For Matrigel injections, after washing in PBS, cells were resuspended in an ice cold mixture of 1:1 PBS and Matrigel (BD Biosciences, Invitrogen Corp.) for a final Matrigel protein concentration of 5 mg/ml. SK-MEL-103 tumors were inoculated into SCID mice (UM breeding strain: 236 C.B-17 SCID, Charles River) at 5×10⁶ cells in 0.1 ml with Matrigel. Treatment was started on day 4-5 after tumor injection.

Xenograft Tumor Growth and Weight Monitoring

The size of tumors growing in the mice was measured in two dimensions using calipers. Tumor volume (mm³)=(A×B²)/2 where A and B are the tumor length and width (in mm), respectively. During treatment, tumor volume and body weight were measured three times a week. After the treatment was stopped, tumor volume and body weight was measured at least once a week and mice were kept for additional 60 days for further observation of tumor growth and toxicity.

Assessment of Toxicity and End Point

Tumors were not allowed to exceed 10% of the animal's total body weight. If an animal had two or more tumors the total weight of all tumors were not allowed to exceed 10% of the animal's total body weight. At the end of the experimental period or when tumor size approached 10% of the total body weight, the animal was euthanized. Animals that showed profound morbidity or a weight loss of over 20% of body weight were euthanized.
